For psychological purposes the most important differences in conation are those in virtue of which the object is revealed as sensed or perceived or imaged or remembered or thought.

The thing of which the act of perception is the perception is experienced as something not mental.

Such being the nature of mental life, the business of psychology is primarily to describe in detail the various forms which attention or conation assumes upon the different levels of that life.

Mental life is indeed practical through and through. It begins in practice and it ends in practice.

You can mark in desire the rising of the tide, as the appetite more and more invades the personality, appealing, as it does, not merely to the sensory side of the self, but to its ideal components as well.

The mental act of sensation which issues in reflex movement is so simple as to defy analysis.

Both expectations and memories are more than mere images founded on previous experience.
